REMAGNETIZING APPARATUS.

Application filed November 12, 1920. Serial No. 428,718.

To all ID/E0772, it may concern Be it known that I, Josnrn (barrow) Bias Nina a citizen of the United States, and a resident of WVebb City, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in i lcmagnetizing Apparatus, of which the following a specification.

The present invention relates to remagnetizing apparatus.

The object of the invention is to provide an apparatus of this character having poles adapted to directly engage the poles of the magnet to be charged and of such construction as to be capable of this direct arrangement without taking down or removing the magnets operated upon from the structure with which they are associated, being espe cially adapt-ed to directly engage the poles of the magnets of the Ford. magneto and to cifectively and efficiently remagnetize these permanent magnets while they are in position on the machine.

Another important object is to provide an apparatus of this character of SliiiPlo, durable and safe construction, reliable in practice and easily manipulated to exercise these functions.

Other objects and advantages of the invention reside in certain novel features of construction combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims reference being had to the accom imnying drawings in which:

l igurc l is a side elevation of the apparatus, parts being shown in section for the 'wurposc of illustration;

Figure 2 is an end elevation; and

Figure is an elevational view, showing the apparatus in operation during the reetizing ol' the magnet of the magnet ing to the drawings wherein then a preferred embodiment of ti the numerals 5 and 6 des '1 the inemliieis of a pair of spaced b. magnetic n'iaterial. T hese bars have their outer free ends adapted to constitute the iioles of the apparatus, as indicated at '7 and. H. Intermediate their ends each of the bars are provided with a circular enlargement 9 having a central opening 10 formaal therein and constituting a bearing. A bridge bar 11 of magnetic material extends between the spaced bars 5 and 6 and its ends are received and retained in the bear-- ings formed by the openings 10 of the enlarged portions of the spaced bars.

A coil 12 is arranged upon the bridge bar 11 and disks 13 of insulating material. are disposed upon the bridge bar 11 between the ends of the coil and the adjacent portions of the spaced bars 5 and 6.

An end cross bar 1-1 of non-magnetic and insulating material extends across and connect-s the inner ends of the spaced bars 5 and 6, the inner ends of course being the ends opposite the poles 7 and 8. Binding posts 15 are arranged upon one of the side faces of the end cross bar 14 to receive the leads 16 from any suitable source of current (not. shown). From the positive binding post a conductor is arranged to carry the current to the coil 12. This conductor comprises a section 18 of wire which leads from the positive binding post to one of the terminals of the single throw knife switch 19 and. the other terminal of this switch is c0nnected by a section 20 of wire to the coil 12. A wire 17 leads from the coil to the negative binding post. It is obvious that when the leads 16 are connected to a source of current and the switch 19 is closed, as seen in Figure 1, the current flows through the coil to energize the apparatus. The bridge bar 11 in this arrangement performs two functions in that it supports the coil 12 and provides a path for the magnet flux.

A handle 21 of insulating material is carried by the top face of the end cross bar 14;.

In practice, the apparatus is grasped by the handle 21 and the poles 7 and 8 of the apparatus are then disposed directly against the poles of the magnet to be energized, as seen in Figure 3. It is to be understood that the north. pole of the apparatus is disposed against the south pole of the magnet to be charged and vice versa: The switch 17 is then closed to energize the magnet. After the required interval the switch 19 is open and the apparatus is then applied to the next adjacent magnet the operation repeat-- ed: and this cycle is carried out until all of the magnets oi the magneto have been reenergized.

I claim:

1. A remagnetizing apparatus of the character described comprising a pair of spaced bars of magnetic material. having their free ends adapted to constitute the poles of the apparatus to directly engage the poles of the magnet to he charged, each of said spaced bars having a portion intermediate its ends enlarged and provided With an opening constituting a bearing, a bridge bar of magneticmaterial extending between said spaced bars intermediate the ends and having its ends supported each in a respective bearing of the spaced bars and thereby magnetically connected With the spaced bars, a coil arranged upon said bridge bar, and an end. cross bar of insulating and nonmagnetic material connecting the ends of said spaced bars opposite the poles of the apparatus.

2. A remagnetizing apparatus of the
